Physical properties of Amida

1. Polar

2. Easily soluble in water due to the presence of group C = O and NH enables the formation of hydrogen bonds.
3. Generally, a solid at room temperature unless: formamide liquid at TR.

Reparation of amides:

Amides are generally synthesized in the laboratory in several ways:
A. Anhydride reaction with ammonia

B. Ester reaction with ammonia

C. Reaction of acid chlorides with ammonia

D. Heating ammonium carboxylate salts

Amide hydrolysis:

Amida is very strong / resistant to hydrolysis. But the presence of concentrated acid or base, hydrolysis can occur producing carboxylic acid.

technically a hydrolysis reaction with water. That's what happens when Amida hydrolyzed with dilute acid catalyst such as dilute hydrochloric acid (HCl). for example in Ethanamida. hydrolysis reaction to form ethanoic acid and ammonia ions.
